Command Line Interface (CLI) The stripe size can be 16, 32, or 64 KB. The default stripe size is 64 KB. Note that you can use the container reconfigure command at a later time to change the stripe size. To create a RAID 5, use the container create raid5 command. In the following example, a RAID 5 is created on devices 0:01:0, 0:02:0, and 0:03:0 using 100 MB of available space from each device. The /stripe_size switch specifies that each stripe contains 64 KB, which is the default if you specify do not specify /stripe_size at all. AAC0> container create raid5 /stripe_size=64K ((0,1,0), 100M) (0,2,0) (0,3,0) Executing: container create raid5 /stripe_size=65,536 ((CHANNEL=0,ID=1,LUN=0),104,857,600) (CHANNEL=0,ID=2,LUN=0) (CHANNEL=0,ID=3,LUN=0) Deleting an Array To delete an array, use the container delete command. In the following example, Array 0 is deleted. AAC0> container delete 0 Executing: container delete 0 After running the container delete command, use the container list command to verify that the array was deleted. In the following example, no arrays are found on the controller. AAC0> container list Executing: container list No containers found. Managing Failover Options and Hot Spares To assign one or more hot spares to a single array, use the container set failover command. To assign one or more spare disks for all arrays, use the container set global_failover command. These commands enable you to add hot spares to an array prior to a drive failure so that the array contains the resources it needs to survive a failure. C-7

Command Line Interface (CLI)
The stripe size can be 16, 32, or 64 KB. The default stripe size is
64 KB. Note that you can use the
container
reconfigure
command
at a later time to change the stripe size.
To create a RAID 5, use the
container
create
raid5
command. In
the following example, a RAID 5 is created on devices 0:01:0, 0:02:0,
and 0:03:0 using 100 MB of available space from each device. The
/stripe_size
switch specifies that each stripe contains 64 KB, which
is the default if you specify do not specify
/stripe_size
at all.
AAC0> container create raid5 /stripe_size=64K ((0,1,0), 100M) (0,2,0) (0,3,0)
Executing: container create raid5
/stripe_size=65,536
((CHANNEL=0,ID=1,LUN=0),104,857,600) (CHANNEL=0,ID=2,LUN=0)
(CHANNEL=0,ID=3,LUN=0)
Deleting an Array
To delete an array, use the
container
delete
command. In the
following example, Array 0 is deleted.
AAC0> container delete 0
Executing: container delete 0
After running the
container
delete
command, use the
container
list
command to verify that the array was deleted. In the
following example, no arrays are found on the controller.
AAC0> container list
Executing: container list
No containers found.
Managing Failover Options and Hot Spares
To assign one or more hot spares to a single array, use the
container
set
failover
command. To assign one or more spare
disks for all arrays, use the
container
set
global_failover
command. These commands enable you to add hot spares to an
array prior to a drive failure so that the array contains the resources
it needs to survive a failure.
